The code builds a system for users to rate their favorite celebrities based on 1-4 stars. Each half star is represented by an HTML radio button, which are each replaced with <a> tags, using background images for the stars.

Everything seems to work fine except that when you click a star/radio button, all subsequent radio buttons are assigned the "checked" attribute. If this were for a real application, and the data was being saved, additional logic would be needed to find the actual radio button/rating the user selected.
